Thread: ODBC + BYTEA

All,

I have some trouble getting a simple SQL working over an
ODBC-Connection.  My Environment:


Client: MS-Windows XP, ODBC-Driver PSQLODBC35W.DLL, Version 08.02.0400
Server: MS-Windows XP, Version 8.2.4


My SQL:

CREATE TABLE "TestTable"
           ( "ColInt"      INTEGER ,
             "ColSmallint" SMALLINT ,
             "ColVarchar"  VARCHAR ( 50 ) ,
             "ColTimestamp" TIMESTAMP ,
             "ColChar" CHAR ( 1 ) ,
             "ColDecimal" DECIMAL ( 8 , 2 ) ,
             "ColBlob" BYTEA ) ;


Now.... when I execute this SQL via ODBC, I get a


<snip>
42704 (7:1260) ERROR: type "lo" does not exist;Error while executing the
query
</snip>



I've googled around a bit and if I got things right "lo" is somewhat an
old-style datatype for binary stuff and nowadays "bytea" should be used.

But why is the ODBC-Driver transforming it into "lo"? And when it is
still in use, why isn't the server recognizing it?


Please bring me in the right direction.....


Bye,
Michael

Try to set

  ByteaAsLongVarBinary = 1

in your ODBC driver configuration. On Windows use Admin Tools / Data
Sources (ODBC) -> PostgreSQL35* -> Datasources -> Page 2 -> play with
the check box "bytea as LO".
